1. A nut runner accessory for a power-driven tool, the nut runner accessory including:
a housing including an open ended slot at a first end portion of the housing;
a gear assembly received in the housing;
an input shaft coupled at a second end portion of the housing and configured to transmit a rotary force from a power-driven tool to an input gear of the gear assembly;
a driver head provided at an output gear of the gear assembly at the first end portion of the housing, the driver head being configured to rotate together with the output gear in response to rotation of the input gear, wherein the output gear and the driver head define an open ended slot corresponding to the open ended slot formed at the first end portion of the housing; and
an alignment device that includes a protrusion moveably coupled into the housing and configured to selectively engage the gear assembly as the input gear and the output gear rotate in response to the rotary force from the input shaft,
wherein, in response to an external manipulation of the alignment device during rotation of the gear assembly, the protrusion is configured to move in a direction parallel to a rotational axis of the input gear or a rotational axis of the output gear and engage a recess in one of the input gear or the output gear and restrict further rotation of the input gear and the output gear, with respective open end portions of the open ended slot defined by the driver head and the output gear and the open ended slot at the first end portion of the housing in an aligned position.
